A muscular, bearded man in a blue drapery stands at the right, holding a large fish in his left hand and gesturing with his right as he looks down at the fish's open mouth. Directly in front of him, a kneeling figure in a vivid red garment leans forward, peering intently at the fish, his hands resting on his knee and his bare feet planted on the rocky ground. To the left, three men in earth-toned robes cluster together, their heads close as they watch the scene unfold, their faces framed by thick beards and hair.

Behind this group, a fifth man with a wild mane of hair and beard gestures with his hand, adding to the sense of urgent conversation among the figures. At the far right, a figure in a pale dress and long hair stands slightly apart, balancing a basket on their head and looking towards the central action. Scattered across the foreground, shells, a crab, and stones are painted with careful detail, anchoring the scene at the edge of water under a bright sky.

The composition draws the group into a tight semicircle, focusing attention on the fish and the dramatic gestures of the figures, while the blue and gold sky opens out behind them. Light falls strongly from the left, illuminating the muscular forms, the folds of drapery, and the vivid red tunic, and casting deep shadows that heighten the sense of volume and movement. The brushwork appears energetic and textured, especially in the rendering of flesh and fabric, with loose, expressive strokes creating a sense of immediacy and life. Saint Peter Finding the Tribute Money was painted by Peter Paul Rubens between 1617 and 1618.
